After an absence of five weeks at a distant possession of mine to which I pay such visits three or four times a year, I find here your favor of Nov. 30.

7Thomas Jefferson to Robert Patterson, 7 March 1811 (Jefferson Papers)
I had thought that the copies of the Nautical Almanac which you had been so kind as to furnish me with some time ago, had included the present year, till I had occasion to use one, and found myself mistaken. having no other medium of obtaining it at present this moment, I have indulged myself with the hope that your friendship would permit me to ask the favor of you to send me that of the...
8Thomas Jefferson to Robert Patterson, 29 May 1812 (Jefferson Papers)
It is long since any occasion presented itself of addressing a letter to you. I avail myself with pleasure therefore of that offered by the papers I now inclose you. they were intended for the society as I judge from the superscription. a long journey soon after their reciept from which I am but just returned, prevented my earlier transmission of them. I was very sensible of the solidity of...
9Thomas Jefferson to Robert Patterson, 9 August 1812 (Jefferson Papers)
I send you another paper from our indefatigable calculator William Lambert . I do not know whether he is a member of our society, but I think his assiduities and qualifications render him entirely worthy of the choice of the society. our literary fare must be of homespun materials, I presume, during the continuance of the war, except so far as we may be refreshed by the precarious reciept of...
